• Zara — on-trend coats, jackets and knitwear (online flagship + in-store pickup).
• H&M — cheap seasonal styles and basics (many NY stores for quick pickup).
• ASOS — huge selection and youthful trends; note ASOS has changed its US fulfillment strategy recently which can make U.S. delivery slower. (thetimes.co.uk)
